Use Actix as base

[JackThomson2]

Actix is a very fast framework and is at the top of the TechEmpowered benchmarks

In my testing it is considerably faster than the hyper backend:

@JackThomson2 , is your PR ready for review or are you still working on it??

[JackThomson2]

@sansyrox Yes it's ready. Key new features are: Much faster performance, ability to set custom response headers and passing the post body to post functions

[sansyrox]

Hey @JackThomson2 👋

Thank you for the amazing work 🚀 .
I have some questions can you please answer them before we move ahead?

Thanks.

[sansyrox]

Can we switch this to individual imports instead of importing everything?

[JackThomson2]

can do, its actix convention in the docs to import all

[sansyrox]

@JackThomson2 , please change it to import specific items instead of an import all and then we can merge this PR.

[sansyrox]

Sorry, approved it by mistake 😅

[sansyrox]

@JackThomson2 , I think if we copy your POST implementation to PUT method, it should also work well imo. What do you think?

[sansyrox]

Hey @JackThomson2 👋
Did you get a chance to look at this PR?

[JackThomson2]

Hi, sorry got pretty side-tracked this weekend, will need a bit of a rebase before we can merge, I'll see if I have time tomorrow

@JackThomson2 , yep yep no worries. I just got really excited after seeing the response time reduce to 1/3rd of itself 😅

[JackThomson2]

Yes it's a huge upgrade, using actix opens a lot more opportunities for file serving or websockets etc.

I'm going to look at implementing https://github.com/davidhewitt/pythonize which would allow us to serialise the json from the rust side rather than python side.

[JackThomson2]

@sansyrox Want to have a look now? Please test this on your machine before merging :)

[sansyrox]

@JackThomson2 , this looks great ✨ . I will test it on my machine today evening and will rebase merge it then.

[sansyrox]

This works well. LGTM 🚀

[sansyrox]

@JackThomson2 , this was an amazing PR 🔥
I had to squash merge this instead of a rebase merge as the conflicts were too much to handle in 2 merge commits.

[sansyrox]

I'm going to look at implementing https://github.com/davidhewitt/pythonize which would allow us to serialise the json from the rust side rather than python side.

@JackThomson2 , I also tried using this but since the incoming response has no fixed structure(read nested json) , I thought it wouldn't be possible to extract the object in a map.

It will be amazing it we could find a way to bypass it.
